An existing outhouse at the far end of the backyard of a house from the 1930s in Porto, used as a storage space without much architectural worth. Thanks to the changes sustained, it is an anachronistic space that devalues the garden. The proposal hollows the construction out, revealing its structural outline, which becomes its façade. The existing space is now generous and suitable, devoid of any obstacle, making up an exterior covered space available for various usages.
